Review of Power Decoupling Techniques for Photovoltaic Micro-inverters
摘要
Abstract
In photovoltaic （PV） grid-connected micro-inverters, the output power contains a pulsation with twice grid frequency while the input power is constant. Usually, electrolytic capacitors of large capacitance paralleled to PV panel are employed to smooth the input voltage and balance the instantaneous input and output power mismatching （power decoupling）. Nevertheless, the life-span of the electrolytic capacitors is too short to meet the requirement of the PV panels, which become the crucial factor of the life-span and stability of micro-inverters. A review of power decoupling methods for micro-inverters in PV system was presented. These methods were categorized and introduced separately. Finally. the comparison and conclusion were t）resented.关键词
